Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a ridging and shaping roller. Background Technology

[0002] In agricultural ridging operations, the ridging and shaping roller is the core component of the deep tillage, inter-tillage, ridging and fertilization integrated machine. Its function is to shape, compact and level the soil after deep tillage and fertilization to form a ridge shape that meets agronomic requirements, providing good soil conditions for subsequent sowing and transplanting.

[0003] The existing ridging and shaping rollers generally have the following problems: First, the overall structural stability is insufficient, and they are prone to deformation due to soil impact during operation, affecting the consistency of the ridging shape; second, the connection between the shaping mechanism and the frame lacks effective buffering and adjustment functions, making it unable to adapt to uneven plots, resulting in poor ridging surface flatness; third, the buffering performance of the leveling mechanism is poor, the scraper is easily damaged due to excessive soil resistance, and the leveling angle cannot be adaptively adjusted, further reducing the ridging quality. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a ridging and shaping roller, comprising a shaping roller body, which includes a support frame, a shaping mechanism, a connecting mechanism, and a ridge surface leveling mechanism. The support frame includes a main crossbeam, a secondary crossbeam, and frames on both sides. The shaping mechanism is fixed to the front end of the frame, and the shaping mechanism includes a shaping roller. The shaping roller is connected to the frame through a roller body bearing assembly at its center. Roller end plates are provided at both ends of the shaping roller, and reinforcing ribs are provided on the roller end plates, with more than one reinforcing rib. Roller teeth are provided on the outer walls of both end faces of the shaping roller.

[0005] The connecting mechanism is symmetrically arranged on the support frame. The connecting mechanism includes a frame connecting part. One end of the frame connecting part is connected to one end of the frame limiting part by a pin. The main body of the frame limiting part is sleeved on the main crossbeam and the secondary crossbeam. The top end of the frame limiting part is connected to the connecting rod by a pin. The other end of the connecting rod passes through the other end of the frame connecting part, and a limiting clip is provided at the end of the connecting rod that passes through the frame connecting part. A frame buffer spring is sleeved on the connecting rod.

[0006] The ridge leveling mechanism includes symmetrically arranged scraper connecting mechanisms, one end of which is connected to the support frame, and the other end of which is connected to the scraper.

[0007] The scraper connecting mechanism includes a buffer limiting member, which is fixed on the secondary crossbeam. One end of the buffer limiting member is connected to the scraper connecting frame via a pin. One end of the scraper connecting frame is connected to the scraper. The other end of the scraper connecting frame is connected to the bottom end of the connecting hinge via a pin. The top end of the connecting hinge is connected to the buffer rod via a pin. The buffer rod passes through the end face of the buffer limiting member, and a buffer mechanism is provided on the side of the buffer rod that passes through the buffer limiting member.

[0008] The buffer mechanism includes a scraper spring, both ends of which are provided with limiting plates, and the limiting plates are all sleeved on the buffer rod.

[0009] The beneficial effects of this utility model are as follows: 1. This utility model adopts the operation sequence design of "scraping first and then shaping". The scraper first treats the unevenness of the original ridge surface, providing a uniform foundation for subsequent shaping, which significantly improves the flatness and consistency of the ridge shape and meets agronomic requirements.

[0010] 2. The main crossbeam and secondary crossbeam of the support frame, together with the side frames, form a stable support structure.

[0011] 3. The connecting mechanism is equipped with a frame buffer spring, and the ridge leveling mechanism is equipped with a scraper spring. The double buffer structure realizes the adaptive adjustment of the leveling and shaping process, which can not only adapt to undulating plots, but also buffer the soil impact force and extend the service life of the components.

The support frame includes a main crossbeam 3, a secondary crossbeam 2, and two side frames 4. The shaping mechanism is fixed at the front end of the frame 4. The shaping mechanism includes a shaping roller 12. The shaping roller 12 is connected to the frame 4 through a roller body bearing assembly 14 at its center. Roller end covers 6 are provided at both ends of the shaping roller 12. Reinforcing ribs 7 are provided on the roller end covers 6, and there are more than one reinforcing rib 7. Roller teeth 5 are provided on the outer walls of the two side end faces of the shaping roller 12. The connecting mechanisms are symmetrically arranged on the support frame. Each connecting mechanism includes a frame connecting part 1, one end of which is connected to one end of a frame limiting part 15 via a pin. The main body of the frame limiting part 15 is fitted onto the main crossbeam 3 and the secondary crossbeam 2. The top end of the frame limiting part 15 is connected to a connecting rod via a pin. The other end of the connecting rod passes through the other end of the frame connecting part 1, and a limiting clip is provided at the end of the connecting rod passing through the frame connecting part 1. A frame buffer spring 16 is fitted onto the connecting rod. The ridge leveling mechanism includes symmetrically arranged scraper connecting mechanisms, one end of which is connected to the support frame, and the other end of which is connected to a scraper 13. The scraper connecting mechanism includes a buffer limiting member 9, which is fixed to the secondary crossbeam 2. One end of the buffer limiting member 9 is connected to the scraper connecting frame 11 via a pin. One end of the scraper connecting frame 11 is connected to the scraper 13, and the other end of the scraper connecting frame 11 is connected to the bottom end of the connecting hinge 10 via a pin. The top end of the connecting hinge 10 is connected to the buffer rod via a pin. The buffer rod passes through the end face of the buffer limiting member 9, and a buffer mechanism is provided on the side of the buffer rod that passes through the buffer limiting member 9. The buffer mechanism includes a scraper spring 8, both ends of which are provided with limiting plates, and the limiting plates are all sleeved on the buffer rod.

[0018] Furthermore, the frame 4 is provided with an adjusting arm reinforcing plate, which is fixed to the outer side wall of the frame 4 to enhance the load-bearing strength of the frame 4 and prevent deformation due to excessive force during operation.

[0019] Furthermore, a beam connecting seat is provided at the connection between the main beam 3 and the two side frames 4. The beam connecting seat realizes the detachable fixing of the main beam 3 and the frame 4 by bolts, which facilitates installation and maintenance.

[0020] Furthermore, the two ends of the frame buffer spring 16 are respectively attached to the end face of the frame connecting part 1 and the limiting clip, and the compression and rebound of the spring are realized by the axial movement of the connecting rod, thereby realizing buffer adjustment.

[0021] Furthermore, the roller teeth 5 are evenly distributed along the circumference of the shaping roller 12, and the top of the roller teeth 5 has an arc-shaped structure to avoid scratching the soil substructure and improve the soil clod breaking effect.

[0022] Furthermore, a wear-resistant bushing is provided at the mating point between the buffer rod and the buffer limiting member 9 to reduce wear during the reciprocating motion of the buffer rod and extend its service life.

[0023] In use, this utility model is fixedly connected to the main frame of the deep tillage, ridge and fertilization integrated machine through the frame connecting part 1 of the connecting mechanism. During operation, the scraper 13 of the ridge surface scraping mechanism first performs preliminary scraping treatment on the unshaped original ridge surface, removing ridge surface protrusions and filling depressions; then the shaping roller 12 rotates around the roller bearing assembly 14 under the action of soil friction, and the roller teeth 5 break up large soil clods in the soil, while simultaneously rolling and shaping the scraped ridge soil; the frame buffer spring 16 buffers the soil impact force on the shaping roller 12 through elastic extension and contraction to avoid damage to the parts, while ensuring that the shaping roller 12 always fits in contact with the ridge surface to ensure shaping consistency; the orderly cooperation of scraping and shaping finally forms a flat and compact standard ridge shape.

[0024] The device is fixed to the main frame of the deep tillage, inter-tillage, ridging and fertilization integrated machine via the frame connection part 1. The integrated machine is started to perform ridging operation. First, the scraper 13 of the ridge surface leveling mechanism performs preliminary scraping on the unshaped original ridge surface, removing protruding soil and filling depressions. Then, the shaping roller 12 rotates around the roller bearing assembly 14 under the action of soil friction. The roller teeth 5 break up the remaining large soil clods and compact and shape the leveled ridge soil. When the field is undulating during operation, the frame buffer spring 16 buffers the impact force through compression and rebound, so that the shaping roller 12 always keeps in contact with the ridge surface. If the scraper 13 encounters stubborn protruding soil, the scraper connecting frame 11 rotates around the pin shaft, pushing the buffer rod to compress the scraper spring 8, realizing buffer adjustment, ensuring the leveling effect while protecting the scraper 13 from damage, and finally forming a flat ridge shape that meets agronomic requirements.

[0025] This utility model proposes a compact ridging and shaping roller. Through a "smoothing before shaping" operation sequence, the scraper 13 first treats the unevenness of the original ridge surface, providing a uniform foundation for subsequent shaping, significantly improving the flatness and consistency of the ridge shape, meeting agronomic requirements. The main crossbeam 3, secondary crossbeam 2, and side frames 4 of the support frame form a stable support structure. Combined with components such as the adjusting arm reinforcing plate and crossbeam connecting seat, the overall structural stability and load-bearing capacity are improved, preventing deformation during operation. The connecting mechanism is equipped with a frame buffer spring 16, and the ridge surface smoothing mechanism is equipped with a scraper spring 8. This double buffer structure enables adaptive adjustment during the smoothing and shaping process, adapting to undulating terrain and buffering soil impact, extending the service life of components. All components adopt detachable connection methods, such as the crossbeam connecting seat and scraper connecting frame 11, facilitating installation, maintenance, and replacement, improving the equipment's versatility and practicality.

[0026] Finally, it should be noted that the above embodiments were selected and described in detail to better illustrate the technical solution of this utility model patent, and are not intended to limit oneself to the details shown. Modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model without departing from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model.
